VALVE-CONTROLLING MECHANISM.

SPECIFICATION formingpart of Letters Patent No. 498,751, dated May 30, 1893.

Application filed August 20, 1892. Serial No. 443,678. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM P. OGDEN, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Valve-Controlling Mechanism; and I do declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it 'appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in means for controlling valves and the object of the improvement is to provide a mechanism which shall prevent the sudden closing of the valve and the consequent strain upon the water pipe with which it is connected, and though specially designed for use in controlling the supply for water-closet basins, it may be employed to advantage in any other suitable relation.

A further object of the invention is to provide a device of this class which shall be of simple construction, economical in cost, reliable, durable and practicable in use.

To these ends the device consists of the features, arrangements and combinations hereinafter described and claimed and will be fully understood by reference to the accompanying drawings in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a side elevation of the device shown in connection with awater-closet basin. Fig. 2 is a vertical section showing the device in detail and on an enlarged scale.

Similar reference characters indicating corresponding parts or elements of the mechanism in the several views let the numeral 5 designate the water closet basin, 6 the pipe for supplying water thereto, 7 the valve interposed therein and 7 the weighted arm connected with the chain, 8 a chain connected with this arm at its outer extremity and leading to a rod 9 attached to the hinged seat 10.

Connected with chain 8 near arm 7 or directly with the arm as may be desired, is one extremity of a rod 12 which is connected at its opposite extremity with an arm 13 attached to the center of a flexible diaphragm 14 closing the top of an air chamber 15 surrounded bya wall 16 carrying a flange 16 surrounding its top, and to which the outer edge of the diaphragm is bolted, a ring 17 of the same width as the flange being laid thereon and secured by the bo1ts,whereby a perfectly air-tight joint is made.

' Communicating with chamber 15 are inlet and outlet air passages 18 and 19 respectively controlled by valves 20'and 21. Valve 20 allows the air to pass freely to the chamber but prevents its exit therefrom, while valve 21 is regulated to control the outlet from the chamber 15 and should be so adjusted as to cause the air to pass slowly out of the chamber. This air chamber is provided with a suitable base 22 whereby it rests upon or may be attached to any suitable support.

The construction shown in the drawings is intended to represent the invention attached to an outdoor water closet. Hence the water pipe 6 and the valve 7 should be located below the freezing point, while the valve-controlling mechanism may be located at any desired point where it is readily accessible for the purpose of controlling the outlet from chamber 15. It will thus be observed that when seat 10 is lowered to the position shown in dotted lines in Fig. 2, the air passing through valve 20 fills the chamber beneath the raised diaphragm. Now when seat 10 is released from pressure the weighted arm 7 a would naturally close the valve 7 quickly, but this it cannot do until the air is expelled from chamber 15'sufficiently to permit the diaphragm to lower to the position shown in full lines in Fig. 2. It will thus be seen that by properly regulating valve 21 the valve 7 may be made to close as slowly as may be desired, thus saving pipe 6 from the strain incident to a sudden cutting off of the discharge therefrom into' the basin.

Having thus described my invention, what I claim is 1. The combination with the water-closet basima seat therefor, the supply pipe, the valve and weighted arm therefor, the latter valve and an adjustable outlet, the diaphragm having an arm attached to its center and a rigid connection between the weighted arm [5 and the valve and the arm attached tothe diaphragm, substantially as described.

In testimony whereof I affiX my signature in presence of two witnesses.

. WILLIAM P. OGDEN.
